Withings Activité

The Withings Activité is a high-end, Swiss-made watch featuring sapphire glass and a calf leather band. Looking at this device, you'd never guess it was anything more than an elegant timepiece. And that's exactly what makes it stand out. This fitness gadget tracks walking, running, sleeping, and swimming, feeding all the data into your smartphone. You can even set an alarm using the Withings app, and have the watch wake you up in the morning by vibrating. The Withings Activité runs on the expensive side, so for those on a tighter budget, the Activité Pop is a more affordable, yet still premium-feeling, option.

How We Tested: The Good Housekeeping Institute called in the newest devices from the most popular fitness gadget makers. We tested each for accuracy in counting steps and monitoring heart rate, and noted how many different metrics it measured. We also looked at battery life, how easy it was to set up the gadget, and whether wearing the gadget caused any irritation. We asked consumer testers to rate their satisfaction levels after using the gadget and its associated app for five days.
